UNITED STATES PATENT orFicE JOHN J. KOHUT, OF ROCHESTER, NEW YORK SHUTTER FOR AUTO HOODS AND LOCKING DEVICE THEREFOR Application filed January 7, 1929. Serial No. 330,746.

The object of this invention is to provide sheet metal. One edge of each slat is rolled an arrangement of a shutter on the inside of around the shaft on which the slat is mounted a hood covering the engine of an automobile, and the slat is fastened to the shaft by pins tractor or flying machine which can be openor set screws. On the end of each of the shafts ed and closed so as to provide ventilation of 3, 4 etc. is fastened a pinion 10, which 55 the space around the engine or to prevent turns with the shaft. Mounted adjacent to ventilation of the space around the engine the angle iron 1 is a rack 11 which engages if desired. all of the pinions of the several shafts so as Another object of the invention is to arto compel all of the pinions and their shafts 1'0 range the ventilating mechanism so that it to move in unison. The topmost shaft is 60 may be more readily operated from the drivturned positively and this through the rack ers seat or from the side of the car to permit and pinions on the other shafts causes all of ventilation or out it off as may be desired. the shafts and slats to turn in unison with Another object of the invention is to proit. The rack 11 is perforated with the slots vide a device by which the shutter may be 12, 13 and 14 through which pass the studs 65 locked in any position desired. 15 with nuts on the ends thereof by which the These and other objects of the invention rack is held in place on the studs. The slots will be illustrated in the drawings, described in the rack permit the rack to move endwise in the specification and pointed out in the on the studs sufficiently to secure the opening claims at the end thereof. and closing movement of the slats. The top- In the drawings: most shaft at the right hand end carries a Figure 1 is a perspective view of the inside pinion 16 that is integral therewith. of the hood showing the slats of the shutter Mounted on the angle 9. is a curved rack 17 and the mechanism for opening, closing and which extends down over the pinion 16. On locking the slats. the under side of the curved rack 17 are car- 75 Figure 2 is a longitudinal section through ried the teeth which are capable of engag the handle and operating mechanism at the ment with the pinion 16. This rack is held upper righthand corner of Figure 1,the hanin place by the bolt 18 at the top thereof, dle being shown shoved into position for opwhich holds it against endwise movement. ht

This rack normally serves to which extend vertically instead of horizonlock the pinion against rotation and thus tally. i 1 holds the slats of the shutter in whatever Figure 5 is a top plan view of a modified position in which they may have been placed. form ofthe operating mechanism for the The topmost shaft extends out to the hanshutter shown in Figure 4, the operating die 25. This shaft is divided as indicated at mechanism being shown placed on the outside 26 and interlocking shoulders are formed on of the hood. y V the ends between the two sections thereof.

In the drawings like reference numerals in- The shaft is divided near the line where the dicate like parts. hood ends and the body of the car begins to In the drawings reference numerals 1 and permit lifting of the hood.

2 indicate angle irons that are mounted on To give a firmer engagement between the the insideof the hood. These angle irons are interlocking shoulders on the ends of the two perforated atcertain places indicated to re sections when they come together, the shaft eeive the shafts 3, 4, 5, 6, 7, and 8 which have itself is made larger in diameter in any suita bearing therein. These shafts carry the able way, as by swaging or upsetting the end 950 slats 9, 9 of the shutters which are formed of of the shaft or shrinking or brazing a sleeve thereon. The outer section of the shaft may be built up in diameter in this same manner or a shaft of larger diameter may be used in the first place. Both sections of the shaft turn in the sleeves 28 and 29. The section 28 of the outer sleeve is fastened in a clamp 30 which holds it against movement either endwise or angular. The sleeve 29 is mounted to slide and turn in a socket 31. On the right hand end of the sleeve section 29 is fastened the handle 32. The handles 32 and 25 can both be moved to theright or left as may be desired; the sleeve 29 is surrounded by a spring 33 which is compressed between the socket 31 and the hub of the handle 32 so that the sleeve 29is normally held in the right hand position shown in Figure 1. When the parts are in the position shown in Figure 2 the two sections of the shaft 27 are in engagement with each other at 26 and they can be turned as a unit by the handle 25 but they are normally locked against rotation by the rack 17 which is in engagement with the pinion 16. I

Carried on the sleeve 28 is an arm 35 which engages under the lower end of the rack 17 and swings it away from the pinion. This arm is moved to lift the rack away from the pinion by the handle 32 and intermediate parts. -When the handle 32 is moved to the right the handle 25 can be moved to turn the shafts 3 to 8 inclusive to open or close the slats. When the handle 32 is released the rack 17 will be pushed back into engagement holding the slats of theshutter in the position in which they have been set.

In Figures 4 and 5 I have shown modifications of this device inwhich the slats 41 are mountedon a series of Vertical shafts 42 to 47 inclusive etc. On the upper end of each of these shafts is provided a pinion 48 which pinion is engaged by a rack 49 by the endwise movement of which all of the slats are turned simultaneously. The shafts 42130 47 inclusive are mounted to turn in angle irons 50 and 51 which are perforated to receive the shafts. The angle iron 50 carries the I studs 52, 52v etc. which pass through slots 53 in the'r'ack bywhich the rack is held in 'po: sition and is permitted sliding engagement.

The rack 49 has an extension bracket 54 on the end thereof in which is swiveled a screw 55. This screw is threaded into a bracket 56 fastened on the hood. .Mounted on the body of thecar is a sleeve 57 which is free to slide in a socket 58 by which it is held in place. On the end of this sleeve is a handle 59. Around the sleeve and between the socket 58 and handle 59 is a spring 60 which normally holds the handle in position shown in Figure 4. The sleeve is slotted as inclicated at 61 and engages with a cross pin 62 mounted in the screw 55. NVhenthesleeve is pushed the sleeve interlocks with the cross pin and the sleeve can then be turned for the purpose of turning the screw and: moving it in either direction with the rack. ,This will cause the slats of the shutter to open or close as may be desired, and because of the threaded engagement between the screw 55 and bracket 56, the rack will remain locked in whatever position it may be left.

The screw 55 and the sleeve 57 are shown divided near the line where the hood ends and the body of the car begins to permit lifting of the hood. 1

In Figure 5 I have shown a handle and a pinion 71 that engages with the teeth 72 formed on the top of the rack 49 by which this rack may be operated from the side of the hood instead of by means of a handle placed within the car. Otherwise the shutter operating mechanism is the same as is shown in Figure 4. The typeof shutter and operating mechanism therefor shown in Figure 5 is probably more desirable in a tractor or fly ing machine while the shutter operating mechanism shown in the remaining figures is more desirable in an automobile. i

It will be understood that a set of these shutters will be used on each side of the hood so as to permit ventilation across the hood through the shutters as well as to permit ventilation lengthwise thr ugh the hood through the radiator. In hot weather if the wind is blowing from the right, the shutter inthe hood on the rightwill be set to catch the wind which will then blow across the engine and pass out on the opposite side of the hood or tofthe rear of theengine. If the wind is blowing from the left, the shutter on the left of the hood will be set to catch the wind which will then pass across the engine in the reverse direction and pass out on the opposite side of the hood, or to the rear of the engine. This adds greatly' to the cooling of theengine; i I claim: 1
